MICROSCOPIC AND MACROSCOPIC DETERMINATIONS OF NUCLEAR COMPRESSIBILITY

摘要

We argue that microscopic calculations remain the most reliable tool for the determination of the nuclear matter compression modulus from the energy of the monopole vibrations of nuclei. Phenomenological expansions of the compression modulus of a nucleus as a function of proton and neutron numbers are ambiguous and cannot yield a precise value for this parameter. Results of new microscopic calculations, with Gogny effective interactions, are presented, These calculations include, in particular, nuclei where pairing correlations are important. They reproduce the available experimental data on heavy nuclei, for a compression modulus in the range 210-220 MeV. [References: 37]
